GRATING AND SLICING DEVICE.

SPECIFICATION forming part of Letters Patent No. 394,759, dated December 18, 1888.

Application filed May 7, 1888. fierial No. 273,157. (No model.)

To all whom it may concern.-

Be it known thatl, JOHN DIsTELHORsT, a citizen of the United States of America, and a resident of Burlington, in the county of Des Moines, State of Iowa, have invented certain Slicing Devices, of which the following is a specification.

This invention relates to means for comminuting horse-radish, nutmegs, roots, and the like, and also for the slicing or cutting into small pieces of potatoes and other vegetables.

The object of the invention is to produce a device for the purposes in question which may be manufactured at small cost and efficiently perform the work intended, and which may be organized for family use and the retail drug trade, and also be capable of being-built of such proportions as to render it available for the use of spice and root grinding establishments. 7

The invention is hereinafter described, and its novel features, for which protection by Letters Patent is desired, are specified in the claims at the end of this specification.

In the accompanying drawings,which form part of this specification, and in which like.

features are indicated by like figures of re erence in the several views, Figure 1 is a view in elevation of the hopper side of a device embodying my improvements. Fig. 1 is a fragment of the grinding or cutting plate, showing the manner of forming the grinding or cutting perforations of Figs. 1 and 4. Fig. 2 is a top view looking down on the hopper, grinding-plate, &c. Fig. 9 is a cross-section through line .r or of Fig. 2. Fig. 3 is a detached view of the grimling-plate shown in Fig. 1, illustrating the arrangement of the perforations. Fig. 4 is a plan view of a moditication of the cutting-plate. Fig. 5 is acrosssection through line y y of Fig 4, and Figs. 6 and 7 are illustrations of modifications of the manner of forming the perforations of the grinding or cutting plate.

Referring to the drawings, 9 indicates the support for the grinding or cutting disk, the said support being of metal and having at its lower end the screwclamp 10, by means of which the device may be conveniently secured to a bench or table. At the upper end of support 9 there is provided a shaft-bearing, 11, and extending therefrom and preferably integral therewith is the hopper-supporting piece 12, the edge 13 of which serves as a scraper, in the manner hereinafter explained.

; The hopper 14 is fixed to its supporting-piece new and useful Improvements in Grating and 12 in any suitable manner that will permit the providing of a space between the same and the scraper-edge 13, within which space the grinding or cutting plate 15 rotates.

As shown, the standard 9, hopper-supporting piece 12, and hopper 14 are formed integral; but they maybe made separately and be secured to one another in proper relative position by any suitable means. The edge 13 of hopper-supporting piece 12 is arranged a slight distance below the adjacent or inner top surface of hopper 14, as shown in dotted lines, Fig. 1, and in Fig. 2, and the hopper itself, preferably, inclines somewhat toward thecutting-disk, so that instead of forming a right angle therewith the angle of approximate juncture is more 01' less acute, as shown in Fig. 2*. I

The grater or cutter 15 is made of tin,steel, or sheet-iron, and is, by preference, of circular form, and it is supported in appropriate relation to the hopper l4 and scraper13 upon shaft 19, which is supported in bearing 11, as shown.

The form and. arrangement of the cutting or grating perforations 23 of plate 15 are such that they will not clog up, and the grated material will not be scattered as itis discharged at the back of said plate, but will be deliv ered in a heap, The perforations 23 are all punched out on the same side, so that one side of the platethe rear side or that with which the scraper-edge 13 of the hopper-supporting piece co-operatesis smooth, the cutting or grating edges of the perforations all being on the hopper side of the plate. The perforations 23 are arranged, for example, as shown in Fig. 3, and the cutting-edges 24 of the same are (in the act of punching out the metal) struck up uniformly, so that as the plate is rotated in the proper direction they will all be presented to the material to be grated or cut. The cutting-edge of each perforation comprises about one-half of its circumference, as shown in 1, and is formed by raising the metal at the back of the perforation. This arrangement of the perforations and their cutting-edges facilitates The passage of the grated material through the perforations.

In Fi g. (5 the perforations 23 are formed with teeth occupying about one-half of the circumference of each perforation, and in Fig. 7 The perforations are cone-shaped with the cuttii'ig-edges 2t formed by raising the metal above the plane of The disk. This last-mentioned construction cuts the substance acted upon into a stringy condition. In Fig. at there is shown a OODSl'l'llCllOll of cutting-disk specially adapted for slicing potatoes and other vegetables and fruits. The plate is divided into Three parts. The cutting-edges 2% are slightly raised above The surface of the adjacent disk-sections and are sharpened, so that by revolving The disk in The proper direction, as imlicated by the arrow, The potatoes or the like are sliced in pieces of uniform thickness.

It is of course to be understood than any of The forms of cutting or gratinplates illustrated may be employed, and The Sill'lStililll'lOll of one form of cutting or grating plate for another is readily accomplished by removing The crank 21.

In using my device the substance to be grated or cut is placed in hopper 1t and held in contact with The plate 15 by the hand, or by any suitable mechanism. Asthe said disk is revolved The cutting-edges of the perfora- Tions 23 repeatedly come in contact with the substance to be connuinuted, thus cutting or slicing the same, as the case may be, in the manner already explained. The cornminuted or sliced material as it passes through the perforations or slits of the plate 15 is scraped ott' said plate by the edge 13 of the hopper supporting piece, which, as explained, occupies a positioi'l just below the top surface of ward the accomplishment of this result.

Ilaviug thus d escribcd my invention, what I claim. as new, and desire to secure by Letters Patent, is

1. In adevice of the character herein described, a support providet'l with a laterallyextended arm, in combination with a revolving cutting-plate, The said arm on one side of said cutting-plate forming a scra1')er and on the other side a hopper-suppivrt, substantially as set forth.

2. The support 5), provided with a shaftbearing and a laterally-extended scraper, in combination with a hopper supported on said laterally-extended scraper in such manner as to form an acute angle of approximate jun eture therewith and to provide an unobstructed space between scraper and hopper, and a cutting-plate mounted to revolve vertically between the hopper and scraper, substantially as set forth.

The support 9, tn'ovided with screwclamp 10, shaft-bearing l1, and combined hopper-supporting piece and scraper l2 13, in combination with hopper 14-, cutting-plate 15, and shaft l S, the cutting-plate secured to shaft 13 and arranged to revolve vertically between the hopper and scra )er, substantially as set forth.
